Partition Of Lin’an Distribution Network Diagnosis And Evaluation Application

In recent years, China’s economic growth mode transformation has exerted a profound influence on the development of power demand, electricity demand growth as the source of driving force, business expansion work also took place great changes, regional power grid how to adapt to such changes become an important problem within a period of time in the future power grid construction. Zhejiang Province, the company annual meeting put forward further change the mode of power grid development, adhere to market-oriented, adhere to the planning guide, innovation lead, hold the government requirements, customer demand, quicken the construction of strong smart grid, strive for the first to build a world-class power grids "the relevant requirements. According to the principle of "taking market as the guide and holding the government’s requirement of customer demand and planning", the breakthrough and innovation of power grid planning concept and evaluation system should be realized.This study aims to through the analysis under the new situation of the development of power demand, in the distribution network diagnostic analysis and evaluation system to be innovative, to the past neglected, and unable to adapt to the new situation evaluation system, to further quantify and supplementary evaluation index, to improve the system of low pressure evaluation, the main work are as follows: to guide the user needs, from the overall to the local in-depth analysis of the main problems affecting the development of distribution network, hierarchical analysis, the establishment of the new situation to adapt to the development of distribution network evaluation index system; using the Delphi method form a unified standard weights and the index value and the evaluation scores between the formation of mathematical logic relation, partitioning between the fitting, try to simulate the characteristics of the index changes, and in accordance with the between different index score difference score standard, forming perfect distribution network evaluation system; the assessment of Lin’an urban counties, towns and rural areas of the county distribution network case, verify the established distribution network comprehensive evaluation system can reasonably reflect the overall development level of distribution network, comparing advantage and disadvantage of different distribution networks and find out the weak links in the distribution network, so as to lay a foundation for the planning, construction and development of distribution network.
